Description
Technical field
The utility model relates to a kind of subway ventilation, air-conditioning equipment systems technology field, belongs to a kind of subway ventilation, air-conditioning multifunctional equipment integrated system.
Background technology
At present, subway ventilation, air-conditioning system mainly contain three part compositions.
The one, the running tunnel ventilating system between underground two stations:
The function of this system is to solve ventilation and the smoke evacuation of train when the obstruction in interval and fire, smoke evacuation during with the station fire, and normal interval the ventilation, for this reason AT STATION two ends be equipped with two large-scalely reversiblely give, the air draft axial flow blower, by give, exhausting duct is connected with ground.
The one, the subway concourse at station, platform public domain are ventilated, air-conditioning system:
At the place that the passenger concentrates, in order to create one than comfortable environment, two ends AT STATION respectively are provided with bigger Air Conditioning Facilities for this reason, or some parts AT STATION are provided with concentrated Air Conditioning Facilities.Be provided with the large-scale combined Air conditioner cabinet in the machine room and return/exhaust blower, and corresponding all kinds of dynamoelectric switching valve door, form an air conditioner ventilating system, undertake the air-conditioning at station and the task of ventilation.
The one, station equipment and management air-conditioning, the ventilating system in room:
Because of this system is an independent design, disturb with the station other system is irrelevant, be not described in detail in this article.
In the metro construction of China, all adopted above-mentioned design, be summarized as by independently running tunnel ventilating system and station air conditioner ventilating system are formed in the system of subway ventilation air-conditioning.From operational effect, can both finish every function that subway ventilation, air-conditioning set, but the place that still has some deficits:
1, the sending of set two large axial flow fans in above-mentioned two ends AT STATION and corresponding earthing face, exhausting duct, all be to be provided with, because of it mainly bears interval the accident ventilation and the smoke evacuation of (train blocks and fire), particularity with the normal interval function of bearing of ventilating, just determined the sands are running out that large axial flow fan started in the whole year, and the cost of this ventilating system is higher, and how making full use of interval accident blower fan system is exactly a problem.
2, according to above-mentioned, the equipment that is provided with in the air conditioner ventilation machine room AT STATION is more, and system is complicated.About the shared about 35m of station total length of two Air Conditioning Facilities, the building length at the tangible like this station of having extended.Because of the subway station is to build underground huge building in, be the structure of an inch of land is an inch of gold, how to save the area of Air Conditioning Facilities, can finish the ventilation at station, the function that air-conditioning sets again, be again a problem.
Summary of the invention
